Hitman42 [59]

Answer:

pharynx, larynx, trachea, bronchi and lungs

The respiratory system is what allows us to breathe and exchange carbon dioxide for oxygen. The human respiratory system is a series of organs responsible for taking in oxygen and expelling carbon dioxide. ... The lungs work with the circulatory system to pump oxygen-rich blood to all cells in the body.

The respiratory system does not work alone in transporting oxygen through the body. The respiratory system works directly with the circulatory system to provide oxygen to the body. Oxygen taken in from the respiratory system moves into blood vessels that then circulate oxygen-rich blood to tissues and cells.
